CLOUDS on BEXUS-38 – dual microspectrometer is on its way to the stratosphere [ 6.25.2026 ]

Logo des CLOUDS-Experiments im REXUS/BEXUS Student Experiment Programme

NEW! The CLOUDS student project from Giessen is set to fly aboard a stratospheric balloon as part of the BEXUS-38 mission. Also on board: a Eurecadual microspectrometer to measure spectral changes in sunlight caused by calcium carbonate particles (CaCO₃).

Learn more about the CLOUDS project in the application example.

CLOUDS stands for »Calcium Carbonate Light Observation Under Stratospheric Dynamics and Scattering«. The team is investigating how CaCO₃ particles alter the incident solar spectrum under stratospheric conditions.

Eureca is supporting the project with a dual microspectrometer as well as technical advice on fiber coupling, calibration, and integration. On our project page, we’ll be providing regular updates leading up to the planned BEXUS-38 launch campaign.
